BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to a portable terminal such as a cellular phone, a PDA (Personal Digital Assistant), an HHP (Hand Held Phone) or the like, and more particularly to a bi-directional sliding-type portable terminal capable of sliding in either direction.

2. Description of the Related Art

In general, a “portable communication device” means an electronic device which a user can carry with him/her to perform wireless communication with a desired partner. In consideration of portability, design of such a portable terminal has tended not only toward compactness, slimness and lightness, but also toward providing multimedia capabilities to allow the user to pursue more various functions. In particular, future portable terminals will be not only used for many functions and purposes despite compactness and lightness, but also be modified to be suitable for functioning in a multimedia environment and for providing internet access and functions. Additionally, such portable terminals may be used by men and women, young and old, anywhere in the world.

Conventional portable terminals may be classified into various types according to their appearance, such as bar-type portable terminals, flip-type portable terminals, and folder-type portable terminals. The bar-type portable terminal has a single housing shaped like a bar. The flip-type portable terminal has a flip which is pivotably mounted to a bar-shaped housing by a hinge unit. The folder-type portable terminal has a folder coupled to a single bar-shaped housing by a hinge unit in such a manner that the folder can be rotated in order to be folded to or unfolded from the housing.

Further, portable terminals may be classified as neck wearable type terminals and wrist wearable type terminals, according to the position at or the way in which a user puts on the terminal. The neck wearable type terminal is one which a user wears around the neck using a lanyard or string, while the wrist wearable type terminal is one which a user wears around the wrist.

Additionally, portable terminals may be classified as rotation-type terminals and sliding-type terminals according to ways of opening and closing the terminals. In the rotation-type portable terminal, two housings are coupled to each other in a manner that one housing rotates to be opened or closed relative to the other while facing each other. In the sliding-type portable terminal, two housings are coupled to each other in a manner that one housing slides to be opened or closed relative to the other. The various classifications of portable terminals are easily understood by those skilled in the art.

Further, each of the conventional portable terminals enumerated above has been converted so as to allow a voice communication as well as a high-speed data communication. That is, as consumer demands have increased, various services have been provided using wireless communication technology for transceiving data at a high speed.

It is a present tendency that a camera lens is mounted to the portable terminal, and that it is possible to transmit image signals and the like.

Meanwhile, present portable terminals are provided with an embedded or external camera lens module. Therefore, it is possible to perform image communication with a desired partner or to photograph a desired subject.

However, when the conventional portable terminals are provided with an external camera lens module, the risk is always taken of losing the camera lens module. Further, when the conventional portable terminals are provided with an embedded camera lens module, a lens of the camera lens module is always exposed to an external environment, allowing foreign materials to easily invade and deteriorate the lens, thus deteriorating the quality of photographed images.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein is omitted to avoid making the subject matter of the present invention unclear.

As shown in FIGS. 1 to 7, a portable terminal according to a first preferred embodiment of the present invention comprises a phone body 10, and a bi-directional sliding body 20 linearly moving on the phone body 10 in a longitudinal direction relative to the phone body 10.

To be more specific, the portable terminal according to the present invention is designed so that a linear movement in either longitudinal direction is carried out while a top surface 10 a of the phone body 10 faces a bottom surface 20 b of the bi-directional sliding body 20, and thus either one side or the other side of the top surface of the phone body 10 is partially opened to a predetermined extent according to a direction in which the bi-directional sliding body 20 moves. Further, the movement range of the bi-directional sliding body 20 is limited by a stopper (not shown), and particularly to a distance large enough to open all of both sides of the top surface 10 a of the phone body 10.

The phone body 10 includes a first section 110 (FIG. 3) which is located on one side of the top surface 10 a thereof and within which a plurality of first keys 102 are mounted, and a second section 112 (FIG. 5) which is located on the other side of the top surface 10 a thereof spaced apart from the first section 110 and within which a camera lens housing 30 is mounted. FIG. 3 shows a state in which the first section 110 is opened, and FIG. 5 shows a state in which the first section 110 is closed.

The phone body 10 has lateral sides, one 10 b of which is provided with a plurality of second keys 120, and a bottom surface 10 c on which a battery pack B is mounted as shown in FIG. 2.

The bi-directional sliding body 20 includes a speaker 210, a display unit 212 and a plurality of third keys 214, all of which are provided on a top surface 20 a thereof.

When moved toward the second section 112, the bi-directional sliding body 20 opens the first section 110 to expose the first keys 102. By contrast, when moved toward the first section 110, the bi-directional sliding body 20 opens the second section 112 to expose the camera lens housing 30. During a stand-by time, the first and second sections 110 and 112 of the phone body 10 are both covered by the bi-directional sliding body 20.

As shown in FIGS. 5 and 6, the camera lens housing 30 comprises a lens 310 and a flash unit 312 adjacent to the lens 310, both of which are mounted on an outer surface in an exposed manner. Here, the camera lens housing 30 is rotatably mounted. To this end, a rotational axis of the camera lens housing 30 is perpendicular to the longitudinal direction in which the bi-directional sliding body 20 slides.

As shown in FIGS. 5 and 7, the second section 112 is formed with an opening 32, in which the camera lens housing 30 is rotatably received. The opening 32 takes a form of a slot S which passes through the second section 112. Therefore, a photograph can be taken of a subject through the lens 310, wherein the subject is oriented toward any one of the top, front or bottom surfaces 10 d, 10 a, or 10 c of the phone body 10.

Additionally, when the bi-directional sliding body 20 slides to cover the first section 110, the portable terminal is automatically converted into a camera photographing mode. This is preferably realized using a separate proximity sensor, which is not shown in the drawings. Further, even when the bi-directional sliding body 20 is closed onto the phone body 10 (see FIG. 6), a desired subject can be photographed by rotating the camera lens housing 30.

As shown in FIGS. 8 to 12, a portable terminal according to a second preferred embodiment of the present invention comprises a phone body 40, and a bi-directional sliding body 50 linearly moving on the phone body 40 in either longitudinal direction while facing the phone body 40. The portable terminal according to the present invention is designed so that a linear movement is carried out while a top surface 40 a of the phone body 40 faces a bottom surface 40 b of the bi-directional sliding body 50, and thus either one side or the other of the top surface 40 a of the phone body 40 is partially opened to a predetermined extent according to the longitudinal direction in which the bi-directional sliding body 50 moves.

The phone body 40 includes a first section 410 which is located on one side of the top surface 40 a thereof and within which a plurality of first keys 401 are mounted, and a second section 412 which is located on the other side of the top surface 40 a thereof spaced apart from the first section 410 and within which a camera lens housing 60 is mounted. The bi-directional sliding body 50 has lateral sides, one 50 b of which is provided with a plurality of second keys 504. The phone body 40 has a bottom surface 40 b on which a battery pack B is mounted as shown in FIG. 12.

The bi-directional sliding body 50 includes a speaker 501, a display unit 502 and a plurality of third keys 503, all of which are provided on a top surface 50 a thereof.

When moved toward the second section 412, the bi-directional sliding body 50 opens the first section 410 to expose the first keys 401. By contrast, when moved toward the first section 410, the bi-directional sliding body 50 opens the second section 412 to expose the camera lens housing 60. These states are shown in FIGS. 9 and 10, respectively.

The camera lens housing 60 comprises a lens 601 and a flash unit 602 adjacent to the lens 601, both of which are mounted and exposed on an outer surface thereof. Here, the camera lens housing 60 is rotatably mounted. To this end, a rotational axis of the camera lens housing 60 is perpendicular to the longitudinal direction in which the bi-directional sliding body 50 slides.

FIG. 11 shows a state of removing a camera lens housing from a phone body. As shown in FIG. 11, the second section 412 is formed with an opening 62, in which the camera lens housing 60 is rotatably received. The opening 62 is formed as a receiving hole. Therefore, the camera lens housing 60 is designed to rotate about a hinge axis in the receiving hole. A photograph can be taken of a desired subject through the lens 601 which is oriented toward any one of the top and bottom surfaces 40 a and 40 b of the phone body 40.

Additionally, when the bi-directional sliding body 50 is moved toward the first section 410, the portable terminal is automatically converted into a camera photographing mode. This is preferably realized using a separate proximity sensor, which is not shown in the drawings. Further, even when the bi-directional sliding body 50 is closed onto the phone body 40, a desired subject can be photographed by rotating the camera lens housing 60.

Further, the bi-directional sliding body functions to protect the keys disposed on the first section 410 of the phone body 40 as well as the camera lens housing 60 disposed on the second section 412 from conditions of an external environment.

As can seen from the foregoing, the present invention employs a construction in that the bi-directional sliding body is mounted on the phone body, so that it is possible to efficiently use the lens of the camera lens housing and to protect the lens from the external environment. In addition, the present invention is designed to allow the bi-directional sliding body to selectively move in either longitudinal direction by push action from a user's finger, so that manipulation of the keys or photographing by the lens can be selected.
